TO ALL WHOM IT MAY CONCERN:

Be it known that 1, AARON D. NOTT, of Fair Haven, in the county of Bristol, and State of Massachusetts, have invented a new Improvement in Swings; and 1 do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side view of my improved swing.

Figure 22 is a vertical section of the same, taken through the line x fc, iig. 1.

VMy invention consists in an 'improved swing, formed by the combination of the double rockers with the upright supports and with the frame from which the platform ofthe swing is suspended; in the combinations lof springs with the double rockers; in the hinge, by means of which the double rockers are pivoted to each other; and in the combination of the braise with the horizontal frame ofthe swing, and with the central connecting-bar of the supports, the whole being constructed and arranged as hereinafter more fully described.

A and B are the upright supports, from and between which the movable part of the swingr is supported.

These supports may be posts set into the ground, or, when it is desired that the swing should be movable, the

lower ends of the supports A and B may be attached to horizontal frames C, and. secured in vertical positions by braces a and b', as shown in fig. 1. To the upper ends of the uprig'lits A and B are attached the stationary rochers D and E, or timbers having their upper sides or edges curved as shown in fig. 2. These curved edges are made with shoulders or flanges upon their outer ed rockers F and Gr from getting out of place laterally. 1l is a cross-bar, connecting the stationary rockers D and E, or the upper ends of the uprights A and B, toveach other, so as to keep them in their proper relative positions. F and G are the movable rochers, the lower or curved edges of which are formed with a'shoulder or iiange upon their inner sides corresponding with the shoulders or anges formed upon the stationary rockers D and E. 1 are the hinges, by means of which the movable rockers are pvotcd to the stationary ones, so that they may be held in their proper relative positions, and at the same time bc free to move or rock. The lower part of the hinges I is secured to the stationary rockers D and E, and its upper end passes up into and is pivoted in a slot formed in the lower edge of the upper part of said hinges. The upper part of the hinges I passes up through a staple attached to the sides of the rockers F and G, so as not to interfere with the movement or rocking of the movable rockers, and at the same time keep them in propel' position upon the stationary rockers. J is the horizontal frame of the swing, from which the platform K is suspended by the timbers L. The frame or timbers J are securely attached to the ends ofthe rockers F and G, so as to move with the movemen of said rockers. l are guard-bars, attached to the timbers L in such a position that the person or persons swinging may take hold of them to steady themselves, if desired; M is a rod, chain, or rope attached to the frame J in such a position that the personV swinging can take hold of it to start the swing. One of these rods, chains, or ropes may, if desired, be attached to each side of the frame J, so aste be in a convenient position in whatever direction the swingers face may be. N is a rod, the upper end of which is attached to the frame J, which passes over the central cross-bar HY, and extends down into such a position as to be easily reached by the person swinging. By pulling upon this rod it is drawn down against the bar H and acts as a brake to stop the motion of the swing when desired. o are springs, one end of which is attached to the stationary rockers Dand E, and their other or free ends rest against the curved lower edges of the rockers F and G, and by their elasticity tend to continuo the movement of the swing when motion has been imparted to it. P is a seat attached to the platform K. R is the hack of the seat P, the side bars r of which pass down through and work in slots formed at the sides of the said seat, and the lower ends of which are pivoted to the side boards or frame of the seat, so that the back, R, may be turned to either side, as may be desired.

Having thus described my invent-ion, what I claim as new, and desire to secure by Letters Patent, is

1. An improved swing, formed by the combination of the double rockers D F and E G, with the supports A B, and with the frame J from which the platform K is suspended by the timbers L, substantiallv as herein shown and described.

2. The combination of th and described and for the purpose set forth.

3. The hinge I, by moans of which tho movable rockers constructed substantially as herein shown and described.

4. The combination of the rod N with the frame J and cross-bar H, substantially as herein shown and described and for the purpose set forth.

The above specification of my invention e springs o with the double rockers D F and E G, substantially as herein shown FG are pivot-ed to the stationaryrrockers D E,
